RAILWAY SAFETY-GATE.

SPECIFICATION forming part. of Letters Patent N 0. 638,667, dated Application filed July 12, 1899. Se

To all whom, it may concern:

United States, residing at Garfield,

Kentucky, have invented certain new and useful Improvements Gates; and I do declare the following to be a of this specification.

This invention relatesto railway safetyga es.

The object of the invention is to provide a railway safety-gate which shall be simple and direction on a trackgates will be automatically lowered, and whereby, also, after a train passes the point at which the gates are placed the latter will automatically be raised.

gate-arms.

Theinvention is illustrated in panying drawings, in which-- Figure 1 is a perspective View of a railwaygate constructed 1n accordance with my invention, the gate-arms being shown in a raised position. Fig. 2 is a side view of one gatethe accomarm, showing in full lines the position of the parts when the gate-arm is lowered and in dotted lines the position of the parts when the arm is raised, the ties being shown in sec- 3 is a plan View of a section of road-bed, showing my gate in position Fig. 4 is a detail View showing the connection Be itknown that I, PAYTON MADISON, a citi- I arms.

When the gate arms are raised, both the fingers c and 61 extend outward away from the rock-shaft, so that a train having a projection H coinin g in either direceach connection G has therein a slot f, of a length corresponding to the distance which the heavy short end of the gate-arm moves to bring the same from a horizontal to a raised position, or vice versa.
